Patented March 10, 1908.

Toall-whom it may-concern:

Beit known that I, LEVI T. SNOW, a citizen of the United States, residing at New Haven, in the county of New Havenand State of Connecticut, have invented a new and useful Improvement in Safety-Razors;

` in connection with the accompanying drawlre resent, in-- ingsand the letters of reference marked thereon, to be a full, clear,v and exact de-l scription of the same, and which said drawings constitute part of this specification, and

igure 1 a view in front elevation of a safety razor constructed in accordance with my invention. Fig. 2 a reverse view thereof with the pivotal locking-lever. shown 1n lts closed position by full lines, and in its partly open position by broken lines. Fig. 3 a view o the device in central longitudinal section. Fig. 4 a view in transverse section on' the line a-1 of Fig.l 3, drawn to an enlarged scale. Fig.- 5 a broken view of the devicein front elevation with the operatingplate removed. Fig. 6 a viewy of the device in front elevation showing the bar like backing plate, the comb andthe locking-lever, the operatingplate`being removed and the lower enjd of the handle being broken away.I Fig. 7 a detached view of the razor-blade. l Fig. 8 any edge viewthereof.

My invention relates to an improvement n safet razors, the object being to produce a simpe and compact device constructed .with particular reference to superior. convenience and effectiveness in use.

With these ends in view my invention con-v flexed to change their Iposition with respect to the cutting edges o the rigid removable razor-bladey 5, which is formed at its respective ends with notches 6 adapting either of its ends to be engaged with 'the -projecting rear e'nd of a stud 7 mounted in the outer end of the backing-piece 3 and with a short stud' 8 projecting a distance represented by the thickness of the blade, from therear face of the lower end of the backing-piece. After engagement with the said studs 7 and 8 the razor blade is locked in place by a lockinglever 9 swinging upon the projecting rear end of a stud 10 mounted in the plate Shear the inner end thereof.

The outer end of the lever 9 is formed with an inclined tongue 11 which shuts into la notch 12 inthe lower face of the rear end of the stud 7, whereby thelocking-lever is .held firmly against the back of the blade the edges of which are rigid with respect to :the teeth of thecomb 4. Now instead of flexing the edges of the razor blade with respect to the teeth of the comb, the edges of the comb areilexed with respect to the edges of the blade. This in width for the engagement of its ed es with thecomb at points just within the ase'sof the teeth'thereof This plate is formed with an opening 14 having'its outer wallformed with a bevel l5 and with an openin 16 .havingrits outer wall formed with4 a evel 1,7. The said openings 14 and 16 provide for the forward projection through them of thestuds 7 and 10, the upper faces of these studsbeing formed with beveled notches 18 and 19.which respectively receive the bevels and 117. For the operation ofthe Vblade 13,'1 provide it with a threaded stem `20` which enters the long tubular stem 21 of a finger-piece v22 which corresponds in diameter to `thehandle 2 and is formed 'with ahub 23 entering the outer end thereof. Now, when ithe dingerpiece 22 is turned from .left to right the bevels 15 and 17 coact with the bevels of the notches 18 vand 19 and force the blade 13 laterally ,forward lwhereby the comb 4 has .its edges deflected toward the edges of the razor-blade 5. Then when the finger-piece is turnedreversely, the resiliency of the comb itself lifts lit away from the edges of the razor-blade to the extent of the outward movement of the the notches 18 and 19.

vention some changes from the construction herein shownv and described may be made. I would therefore have it understood that I do not limit myself thereto but hold In self at liberty to make such departures there rom is done bymeans of an operating-.plate 13 concavo convex 1n cross-sectlon andiadapted cams 15 and 17 with respect to the bevels of It is apparent that in carrying out myzinl edged razor blade vagainst the rigid therewith,

as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is :k

l. In a safety razor, the combination with a handle, of an 'alined backing-piece rigid therewith, a flexible double-edged comb applied to the back of the backing-piece and rojecting beyond the -edges thereof, means or holding a double-edged razor blade against the back of the comb, and means placed 'overl the front of the comb for engaging with the edges". thereof for deflecting the said edges with respect to the edges of theblade.

2'.' vIn a safety razor, the combinationwith a handle, of an alined backing-piece rigid therewith, a flexible double-edged comb applied to the back of the backing-piece and projecting beyond the edges-thereof, a lock 1ng`lever pivoted at one end for holding a double-edged razor blade against one face of the comb with which it is alined when it is illits closed position, land means applied to the opposite face of the comb for engaging with the edges thereof for defleeting the said edges with respect to the edges of the blade.

3. In a safety razor, the combination with a handle, of an alined backingpiece rigid therewith, a fiexible double-edged comb applied to-the back of the backing-piece and projecting beyond the edges thereof, means for holding a double-edged razor blade against the back of the comb, an operating-plate placed over the front of the comb and engagmg with the edges thereof for flexing the same with respect to the edges of the blade, and means for connecting the saidA plate with the backing-piece for moving it laterally with' respect thereto and for connecting it with the handle for its longitudinal movement.

4. ln a safety razor, the combination willi a handle, of an alined l' acl{ing-piece rigid therewith, a longitudinally flexible doubleedged comb applied to the back of the backing-piece and projecting beyond the edges thereof, a locking-lever pivoted at its inner end to the inner end of the backing-piece and adapted to hohl a double-edged razor blade against the back of the backing-piece with the outer end of which its outer end is coupled when it is alined with the comb, and means coupled with the backing-piece and with the handle for engagement with the front of the comb for flexing the same with respect to the edges of the blade.

5.

6. In a safety razor,'the combination with a tubular handle, of an alined backing-piece rigid therewith, a longitudinally flexible double-edged comb applied to the back of the backing-piece and projecting beyond the edges thereof, .means lor holding a doubleedged razor blade against the back of thc backing-piece, a. longitudinally arranged op erating-plate for engagement willi the front Yo'f the comb for flexing the same longitudinally with respect to the edges of the blade, the said )late having a shank extending into the tubiflar handle, means for coupling the operating-plate with the backing-pinze for its lateral movement with respect thereto, and means located in thetubular handle and engaging with the shank of the operatingplate for moving the same longitudinally.

7. 1n a safety razor, the combination with a .tubular handle, of an alined backing-piece rigid therewith, a longitudinally flexible double-edged comb applied to the back of the backing-piece and projecting beyond the edges thereof, means for holding a doubleedged razor blade against the back of the comb, studs mounted in the backing-piece, an operating-plate coacting with the said studs for its lateral movement with respect to the said limiting-piece and engagingwith the front ol' the comb for flexing it with respect tothe edges of the blade, and means mounted in the handle for moving the operating-plate longitudinally.
